Material removal tool (), such as for forming surfaces of valve seats, includes an integral or separable reduced diameter circumferential insert housing () including a plurality of inserts () bonded thereto. The plurality of inserts () include cutting surfaces () at different axial and radial positions relative to the axis () of the material removal tool (). Cutting surfaces () at different axial and radial positions are arranged at different angles to the axis (), and at least one cutting surface () on at least one insert is at an angle of about 45 degrees relative to the axis (). Cutting surfaces () can be located on one insert-type or different insert-types and can have different combinations of cutting surfaces (). When arranged circumferentially on the insert housing (), a N-effective material removal tool () is formed. Methods of machining using the N-effective material removal tool () is also disclosed.

Multi-effective material removal tool

A machine tool system includes a clamping unit installable on the head of a cutting machine, and a tool holder insertable into the clamping unit. The clamping unit includes an annular guide member and a sleeve telescoped onto the guide member. A flat drive key is positioned in an axial slot in the sleeve to establish a driving connection between the clamping unit and the tool holder. The tool holder is wedged into the clamping unit by means of radially-movable wedge lock elements and an axially movable drawbar.

Machine tool system

An adjusting locator to adjust the axial position of a cutting insert in a cutting tool to eliminate cutting run out. The locator is comprised of a body, a flex flange substantially parallel to the body and spaced from the body by an adjusting groove. The flange is connected to the body by a bridge, which is defined between the adjusting groove and a flex groove whereby the flange flexes using the bridge as the fulcrum of the flex.
